ACUS03 KWNS 210712 SWODY3 SPC AC 210711 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0211 AM CDT Sat Mar 21 2026 Valid 231200Z - 241200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CAROLINAS AND GEORGIA... ...SUMMARY... An isolated severe threat is expected on Monday across parts of the Carolinas and Georgia. ...Carolinas/Georgia... An upper-level trough will move eastward to near the Eastern Seaboard on Monday. At the surface, a cold front is forecast to move through the Carolinas, and should be positioned from central Georgia into central South Carolina by Monday afternoon. Ahead of the front, surface dewpoints in the upper 50s and lower 60s F will contribute to weak destabilization. Isolated thunderstorms are expected to develop near the front and move east-southeastward toward the Atlantic coast during the mid to late afternoon. 0-6 km shear in the 30 to 35 knot range, along with steep low-level lapse rates may be enough for a marginal wind-damage threat. ..Broyles.. 03/21/2026 $$
